Tekran Instruments Corporation is the world’s leading manufacturer of advanced systems for ambient and point-source mercury monitoring. With pioneering expertise in cold vapor atomic fluorescence detection, Tekran® has become the trusted source for accurate and reliable measurement of ultra-trace mercury levels. Tekran has provided more ambient and CEM systems than any other supplier worldwide.

About Us


Tekran was founded in Toronto, Canada in 1989 to develop custom analytical instrumentation for environmental analysis. Our first analyzer, the Tekran 2537, was introduced in 1993 and is now widely accepted as the gold standard for automated ambient air analysis of mercury. Tekran continues to expand and improve our product lines, which are focused exclusively on instruments and systems for mercury measurement. We now offer systems for ambient air mercury speciation monitoring, automated analysis of total mercury and methyl mercury in environmental samples, total mercury in natural gas, and mercury continuous emission monitoring of coal-fired power plants and other industrial emission sources. We also offer a wide range of secondary equipment to support our main product lines.

Who We Are

Tekran Instruments Corporation is the world’s leading manufacturer of advanced systems for ambient air, laboratory analysis, and point-source mercury monitoring. With pioneering expertise in cold vapor atomic fluorescence detection, Tekran has become the trusted source for accurately and reliably measuring ultra-trace levels of mercury. Tekran has provided more automated air analyzers and Hg-CEM monitoring systems than any other supplier worldwide.

What We Do

Tekran is an international leader in environmental measurement technology, serving the needs of industry, government and research institutions with applications ranging from pure research to primary manufacturing. We revolutionized continuous mercury monitoring through the use of cold vapor atomic fluorescence spectrophotometry and pure gold preconcentration. Tekran’s systems for ultra-trace measurement of mercury in ambient air, stack emissions and environmental samples are extraordinarily sensitive and robust with detection limits of less than 1 picogram absolute and practical immunity to interfering compounds.


Tekran is known worldwide for the accuracy and dependability of our equipment and will continue to exceed customer expectations. From developing the industry’s first proven ambient air analyzer and mercury Hg-CEMs, Tekran has been at the forefront of the mercury measurement industry since 1992. For example, the Tekran 3310 Elemental Mercury Calibration Source was chosen by the US National Institute of Standard and Technology (NIST) as the “NIST Prime” which is used to certify all other Hg-CEM calibration sources.
Tekran’s research and development efforts continue to be headed by cofounders Frank Schaedlich and Dan Schneeberger. Our unique solutions and industry leading designs have been awarded numerous patents. With our growing staff of research engineers and technicians, the Tekran team leads the way with employee commitment to innovation, quality and customer service. As we pursue future opportunities, we know Tekran has the people, technology and resources to measure up to your standards and ours.


As a member of the TSI family, Tekran is backed by world-class design, manufacturing and customer support facilities that position us to meet the demands of a global market. TSI Incorporated provides Tekran with the ability quickly ramp production, delivering large scale mercury monitoring solutions to industry. For more information, see www.tsi.com.


Tekran - Model 2505 - Mercury Vapor Primary Calibration Unit

The Tekran Model 2505 mercury vapor calibration unit was designed to provide a traceable external standard to audit the Tekran 2537 internal mercury calibration source. However, the Model 2505 provides an accurate and reproducible means of injecting a known quantity of elemental mercury vapor into any analytical system. Since the saturation vapor concentration of mercury is a well known function of temperature, only the exact volume injected and ...

Tekran - Model 1110 - Synchronized - Two Port Sampling System

The Tekran Model 1110 Synchronized Two Port Sampling System gives the Model 2537 Mercury Vapor Analyzer the ability to sample two unique sources. Switching between the two sources is synchronized with the instrument sampling cycle and is fully programmable by the user. This is particularly useful for flux chamber studies to measure inlet and outlet concentrations, or gradient flux measurements at different heights. If desired, multiple 3-way valves ...


Mercury monitoring for manual analysis of air traps

The Tekran 2600 versatility is evident with the economical and convenient configuration for manual analysis of air samples collected on gold cartridges. Converting the instrument allows calibration by simple injection of gaseous Hg using the Tekran 2505. Once analyzed, the gold cartridges are immediately ready for redeployment.

Mercury monitoring for measuring mercury speciation in air

Tekran offers the only completely integrated, automated system for measuring mercury speciation in air. The Tekran 2537, when coupled to the Model 1130 and Model 1135 provides a continuous record of gaseous elemental mercury, gaseous oxidized mercury and particle-bound mercury. Over the past 12 years, the Tekran 2537-1130-1135 system has been the most significant tool used to advance the understanding of the fate and transport of atmospheric mercury. See the Expert’s Corner for details about international...


Calibration / Recertification Services

Tekran offers recalibration services for all our products. We utilize specialized NIST traceable instruments tasked specifically for calibration and recertification of our instrumentation. We also offer complete systems evaluation whether part of your maintenance schedule, or to quickly access an instrument that has set idle for a long period.

Hg-CEM System Services

For our Hg-CEM product line, we offer a wide range of support services tailored to fit your needs. Our engineering experts are available to install the Hg-CEM at your location, and we can provide support to integrate our Hg-CEM into any existing data acquisition system. Tekran Hg-CEM training courses even have options for online attendance.


Hg CEM & Laboratory Training

A well structured training program pays immediate dividends, and our customers tell us Tekran training programs are among the best. It takes a well trained operator to get the highest performance out of their analytical equipment. At Tekran, we have spent considerable effort developing comprehensive training programs to provide our customers the needed skills and knowledge to become adept mercury analysts.
